Question

A micrometer increments how far for each complete rotation of its thimble?

1) 0.025
2) 0.205
3) 0.025
4) 0.0025

Answer 1

Each complete rotation of a micrometer's thimble advances it by 0.025 millimeters (25 micrometers).

Step-by-step explanation:

A micrometer is a precision measuring instrument used by engineers and machinists. For each complete rotation of its thimble, a typical micrometer advances by a set increment. The increments are standardized, and in the question, you're offered four numerical options. Checking these options against standard micrometer increments, the correct answer is that a micrometer advances by 0.025 millimeters (also written as 25 micrometers) for each complete rotation of its thimble, which is option 1).
